------- Comment #2 from Tim-Philipp Müller  2008-06-02 18:39 UTC -------
This seems to fix it for me:

 2008-06-02  Tim-Philipp Müller  <tim.muller at collabora co uk>

        * ext/pango/Makefile.am:
        * ext/pango/gsttextoverlay.c: (gst_text_overlay_shade_y),
          (gst_text_overlay_blit_yuv420), (gst_text_overlay_push_frame):
          Use gstvideo functions to calculate strides and plane offsets. Fixes
          rendering issue ('ghost' images of the text on the chroma planes)
          with widths or heights that are not multiples of 8 (#506659 and
          probably also #485729).

        * tests/icles/test-textoverlay.c: (show_text), (test_textoverlay),
          (main):
          Test with odd height/width too.


Please re-open if you still have issues with that fix applied.
